Product details
Danfoss TGE Thermostatic Expansion Valve | R410A & R32 | 067N3152
Product Description: The 067N3152 is engineered to handle the rigorous demands of modern, high-pressure cooling systems. In the UAE’s intensive HVAC market, this valve is a critical component for ensuring efficiency in rooftop units and water chillers. Its hermetic construction, featuring an all-laser-welded design, minimizes the risk of leaks—a vital factor for high-pressure R410A and R32 systems. The integrated balanced port technology ensures stable performance even when head pressures fluctuate during the peak heat of a Dubai summer. Its stainless steel power element ensures longevity and resistance to corrosive coastal environments.
Key Features & Benefits:
- Dual Refrigerant Compatibility: Fully optimized for R410A and the low-GWP refrigerant R32, supporting UAE’s green building initiatives.
- Balanced Port Technology: Guarantees stable refrigerant flow despite wide variations in ambient temperature and head pressure common in the Middle East.
- Leak-Proof Hermetic Build: Laser-welded copper and stainless steel construction eliminates potential leak paths for maximum system integrity.
- High-Pressure Reliability: Specifically built to handle operating pressures up to 46 bar, typical of modern UAE cooling installations.
- Bi-metal Solder Connections: Simplifies the brazing process for UAE technicians, ensuring a safe installation without damaging internal components.

FAQs:
- Q: Is the 067N3152 suitable for R32 systems in the UAE?A: Yes, it is specifically rated for R32, which is increasingly common in new, high-efficiency AC installations across the UAE.
- Q: Why is the “Balanced Port” important for Abu Dhabi installations?
- A: It prevents the valve from “hunting” or becoming unstable when outdoor temperatures—and thus condensing pressures—are extremely high.
- Q: Does this valve require regular maintenance?
- A: Due to its hermetic, all-welded design, this valve is maintenance-free. If it fails, the entire unit is replaced to ensure a leak-proof system.
